How I can reset the Huawei Lion Battery ESM48100, by the way I have a software "batterymodbustool" and I can connect to the battery with an adapter and minitor voltage, temp, alarms .. etc but I can't change anything. Can anyone send me a tool to enable me changing parameters and reset the alarms?

Many thanks
